Automatic update from web-platform-tests
[Azure Pipelines] Upgrade to macOS 11 (Big Sur) (#30256)
This moves to using acceptInsecureCerts with a new enough release of
Safari, which removes the blocker to running STP on Azure Pipelines
documented in #31147, whereby trusting certificates in Big Sur or
later requires either user interaction or SIP being disabled, which is
infeasible on Azure Pipelines. See
https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-release-notes#Security
for details about the behaviour change in Big Sur.
For now, this keeps Safari (stable) on Catalina, as it doesn't support
acceptInsecureCerts.
Additionally, this moves all usage of Python on Big Sur to 3.7, as 3.6
is not available Azure Pipelines' macOS 11 VMs.
